NAME¶
Moose::Meta::TypeConstraint::Class - Class/TypeConstraint parallel hierarchy
VERSION¶
version 2.0603
DESCRIPTION¶
This class represents type constraints for a class.
INHERITANCE¶
"Moose::Meta::TypeConstraint::Class" is a subclass of
Moose::Meta::TypeConstraint.
METHODS¶
- Moose::Meta::TypeConstraint::Class->new(%options)
- This creates a new class type constraint based on the given
%options.
It takes the same options as its parent, with two exceptions. First, it
requires an additional option, "class", which is name of the
constraint's class. Second, it automatically sets the parent to the
"Object" type.
The constructor also overrides the hand optimized type constraint with one
it creates internally.
- $constraint->class
- Returns the class name associated with the constraint.
- $constraint->parents
- Returns all the type's parent types, corresponding to its
parent classes.
- $constraint->is_subtype_of($type_name_or_object)
- If the given type is also a class type, then this checks
that the type's class is a subclass of the other type's class.
Otherwise it falls back to the implementation in
Moose::Meta::TypeConstraint.
- $constraint->create_child_type(%options)
- This returns a new Moose::Meta::TypeConstraint object with
the type as its parent.
Note that it does not return a
"Moose::Meta::TypeConstraint::Class" object!
- $constraint->get_message($value)
- This is the same as "get_message" in
Moose::Meta::TypeConstraint except that it explicitly says "isa"
was checked. This is to help users deal with accidentally autovivified
type constraints.
